With !600 (merged) the format of the dependencies column
tx_terfe2_domain_model_version was changed from
serialized to JSON.
In !601 (merged) a CLI command was introduced which
generates "compatible TYPO3 versions" data from these
column. This CLI command however only evaluated the data
in the old format.
Therefore a fallback is being implemented to support both
formats, so it doesn't matter which command is executed first.
